[hibernate-issues] [Hibernate-JIRA] Commented: (HBX-1074) DelegatingReverseEngineeringStratey.columnToHibernateTypeName reports invalid values

[James Wilson (JIRA)]

    [ http://opensource.atlassian.com/projects/hibernate/browse/HBX-1074?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=35273#action_35273 ] 

James Wilson commented on HBX-1074:
-----------------------------------

We are also having this problem. For Oracle views with columns of type NUMBER with no scale, the reveng tool reports their scale as 0. This means that, if you have 

   <sql-type jdbc-type="DECIMAL" scale="0" hibernate-type="java.lang.Long" />
   <sql-type jdbc-type="DECIMAL" hibernate-type="java.lang.Double" />

in your reveng config file, these columns will be mapped to Long and the decimal portions of their values will be truncated.

Let me know what you will need in terms of a test case. (I just signed up and I'm new to your procedures.)

>             Project: Hibernate Tools
>          Issue Type: Improvement
>          Components: reverse-engineer
>    Affects Versions: 3.2.1
>         Environment: MyEclipse w/ Hibernate rev engineering against Oracle 10g
>            Reporter: Joel Schuster
>
> When implementing an extention to the [u]DelegatingReverseEngineeringStrategy [/u]the [u]columnToHibernateTypeName [/u]does not report the true value of the [b]precision [/b]and [b]scale [/b]column of the table description/definition.
> The method signature:
> [code]@Override
> 	public String columnToHibernateTypeName( TableIdentifier table, String columnName, int sqlType,
> 	                                         int length, int precision, int scale, boolean nullable,
> 	                                         boolean generatedIdentifier) {[/code]
> The precision and scale parameters are [b]int[/b]. If the values in the definition are [b]null[/b] the values reported here come out as DATA_LENGTH and 0. Not null.
> These parameters should be [b]Integer[/b] and be set to [b]null [/b]when applicable.
